AMP Problem after the latest update

Hello,
I am getting some internal server problem just after updating to the latest version. The information of the problem is at the footer of all amp pages and have attached one of my pages.
Kindly do help and thanks for such an easy plugin to use. I believe it was made for non-techies like me because it’s easier compared to other amp plugins.
